The report:

Hello, between 1981 and 1983 I was preparing my BEP and CAP in electrotechnic, one days at the quatres chemins of Aubervilliers where my college was, I saw in the sky an enormous green luminous ball coming from Le Bourget and going towards La Villette thus it followed a rectilinear trajectory like main road 2, then it changed direction into making a kind of hyperbole to go up in the sky and to disappear at an incredible speed and without noise.

Much later, I had an idea (for the scientists), why not trye to rather travel with the light than to try to manufacture rockets which will never reach the speed of light?
